VOIP by VPN

[nsoares]

Hi Everyone,

I have a VPN conection to my ClusterXL Checkpoints (4200 appliances). Everything works fine, except VOIP calls.

I can sucessfully make a conection to my voip server, make voice calls from the internal network to the external network, but when I make calls from the external network to the internal network, get this error:

"

Firewall - Protocol violation detected with protocol:(RTP), matched protocol sig_id:(1), violation sig_id:(9). (500)

"

What can I do? Without compromise my security?
